The hub, disk and brake-drum are connected together by means of bolts 22 passing through the hub flange 13, the plane portion 15 of the disk and the oHset portion 19of the brake-drum and having nuts 23 screwed thereon.' These bolts preferably pass through the parts between the radial corrugations, as best shown in Fig. 3. l

The provision of the central offset portion strengthens the brake-druin materially and reinforces it against the strains imposed upon it, which are often quite severe in practice. Furthermore, this offset portion 'simplifies very much the construction of the hub, reduces the amount of material necessary to` form the hub and eliminates the necessity of any fillers between the disk and the brakedrum. VThe radial corrugations formed in the central portion ofV the'brake-drum alsov assist materially in strengthening andstiening it and theradial corrugations formed in the central lportion of the disk have the same effect upon that part of the structure. Furthermore, since the corrugations in the brake-drum interlock with the corrugations of the disk, the torque resulting from the application of the brakes is transmitted directly Jfrom the brake-drum to the Vwheel disk and the bolts 22 and nuts 23 merely serve to clamp the parts together and are not relied upon to resist these stresses and strains resulting from the application of the brakes. This Y makes a very simple and cheap construction but one which is exceptionally strong and efficient in practice. Y

I am aware that the invention disclosed herein may be varied considerably without tral opening being rearwardly curved to form a flange mounted on the barrel of said hub, a brake-drum having a central portion oset to forma vertical` wall fitting against the central plane portion of said disk and having radial corrugations interlocking with the corrugations of said disk, said brake-drum having a rearwardly curved flange immediatelyvadjacent the central opening and litting the cylindrical barrel of said hub, and means connecting said brake-drum, disk and hub together.
